Is Rupert Murdoch's quest to take over Time Warner over just because he says it's over?

That's what media watchers are asking each other now that Murdoch has "walked away" - his words - from 21st Century Fox's proposal to acquire Time Warner, the parent company of CNN.

Some are relieved. Some are disappointed. And some... don't buy it at all. Since Murdoch's statement on Tuesday, I've talked to plenty of people whose reactions can be summed up with three words: "This isn't over."

In this Web-exclusive video, Brian Stelter talks with New York Times media columnist David Carr and Business Insider co-founder and editor in chief Henry Blodget about Rupert Murdoch's bid for Time Warner. On Wednesday Time Warner said it had rebuffed Murdoch - but what might happen next?

Transcript of the conversation:

STELTER What is the likelihood of Time Warner being sold, in some way, in some form?

CARR: Well Henry's better at this stuff, but usually once something gets kicked into play, it doesn't get kicked back out of play. What you end up talking about is, 'What is the number?' Not 'Is it going to happen,' but 'When is it going to happen.'FULL POST

We’ve got a busy show planned this Sunday when Brian Stelter of the New York Times returns to guest host ‘Reliable Sources.’ We’ll discuss the latest coverage out of Syria amid rising tensions in the region, but until then, here are some other stories that caught our attention this week:

‘Why bloggers fell for a fake TechCrunch story about self-driving cars’ Slate’s Will Oremus took note of a recent TechCrunch story titled ‘Dispatch from the Future: Uber to Purchase 2,500 Driverless Cars From Google.’ Only problem? The post, complete with a July 25, 2023 dateline, was fictional. That didn’t stop some journalists, who tweeted, blogged and incorporated the post into their stories as though it were factual. While Google announced its plans to invest $258 million in the car-service mobile app earlier this month, it appears that, for now, entire fleets of driverless cars are still a phenomenon of the future.

He’s one of the most well-known media moguls in the world, and Rupert Murdoch is now adding wineries to his list of acquisitions. Politico reports this week that Murdoch is in the process of closing a $28.2 million deal to buy a combo estate/vineyard in the Bel Air neighborhood of Los Angeles. Spanning 13 acres and 7,500 square feet, the property was originally owned and built by Victor Fleming, director of Hollywood classics like ‘The Wizard of Oz’ and ‘Gone With the Wind.’

‘Will this be the tweet heard ‘round the world?’ The Washington Post’s Dominic Basulto speculates what Twitter can learn from Facebook’s 2012 IPO amid rumors that the social media giant could also go public in 2014. He notes that if/when and IPO should arise, Twitter would join other publicly traded media companies like Google, Instagram, and Linked In. Basulto writes that as social media companies expand, so does Wall Street’s influence and a subsequent focus on mobile platforms to generate revenue.

Famed crime/suspense novelist Elmore Leonard passed away August 20, but his writing expertise is the focus of several never-before seen videos. In two videos, Buzzfeed highlights Leonard’s 10 rules for writers. His tips range from lighthearted to serious, including ‘try not to show off with your writing,’ and ‘try to leave out the parts that writers skip.’ Over his lifetime, 26 of Leonard’s books were adapted into screenplays.

‘No, ‘twerk’ and ‘selfie’ have not been added to the Oxford English Dictionary’ ‘Twerk’ was the word of the week after Miley Cyrus’ over-the-top VMA’s performance, but the word caught people’s attention for another reason, too. Critics were quick to point out that ‘twerk’, among other words, was not added to the Oxford English Dictionary, but added to the separate entity, Oxford Dictionaries Online. Multiple media pundits were quick to pick up on the error, but not before several outlets misreported the additions. Among other notable words added to Oxford Dictionaries Online were ‘selfie,’ ‘emoji’, and ‘food baby.’

Rupert Murdoch agrees to face Members of Parliament again as the investigation into News Corp continues. David sits down with former MP Louise Mensch who once grilled Murdoch and now writes a column for the Sun.

After more than a year of non-stop media coverage, protests and court hearings, the George Zimmerman trial is set to wrap up in the next few days. All three 24-hour news networks have spent the past few weeks producing wall-to-wall coverage of the murder trial - but how fair has the coverage been to the prosecution and to the defendant? Callie Crossley, host of WGBH's "Boston Public Radio" will join our guest host, NPR's David Folkenflik, to discuss.

Next, The Guardian's Ana Marie Cox, The Washington Post's Carlos Lozada and The Atlantic's Molly Ball swing by the studio to weigh in on Mark Leibovich's new book, "This Town," which focuses on inside-the-beltway relationships between politicos, the press and the parties they attend together. Luckily for us, Lozada says there are 10 rules for succeeding in "This Town" (aka Washington D.C.). Can you guess what they are?

Jumping a topic train from DC politics to New York election races, our group adds former New York Post reporter Leela de Kretzer to discuss tabloid coverage of Eliot Spitzer's and Anthony Weiner's upcoming bids for NYC comptroller and mayor, respectively. But as Ball wrote earlier this week in the Atlantic, "If Spitzer and Weiner manage to join Sanford in getting elected post-sex scandal, they won't be signaling a bold new trend. They'll be doing what politicians have always done: getting in trouble and then getting elected anyway."

Rupert Murdoch has agreed to testify before the British Parliament following the leak of a secretly taped recording where he has an ethically questionable conversation with News Corp journalists. Former Member of Parliament Louise Mensch, who questioned Murdoch during his original testimony to Parliament, joins Folkenflik to share her insight into the secret tape and what it's like to now work for one of Murdoch's newspapers, The Sun.

Next, former Al Jazeera English anchor David Marash and NPR's Cairo bureau chiefLeila Fadel weigh in on Al Jazeera's struggle with editorial independence and coping with the Egyptian military following recent Egyptian protests in Cairo.

Rounding out the show, president and general manager of WDRB Louisville Bill Lamb tells Folkenflik why his station is moving away from the "breaking news" hype.

As I wrote today, the media mogul tarnished his reputation with a stunningly offensive Twitter message on how the “Jewish owned press” was consistently “anti-Israel” in time of crisis. This raised such questions as: What Jewish-owned press? Anti-Israel for, what, twisted religious reasons? And, why doesn’t someone keep this 81-year-old News Corp. boss away from the Twitter?

Well, someone got to Rupe, because he finally figured out by this afternoon that he had to do a full grovel.
